Thermoelectric properties of hot-pressed YbAl/sub 3/ compound over temperature range 150-800 KSmall crystals of YbAl/sub 3/ have been obtained using the Bridgman or a direct synthesis method and subsequently disc-shaped compacts prepared using a hot-pressing technique. The Seebeck coefficient, ...
Samples were embedded in optimal cutting temperature compound (OCT) (VWR) and stored at −80 °C. Tissue was sectioned onto slides at 14 μm using a cryostat. Tissue slides were postfixed in 10% normal buffered formalin (VWR) for 10 min and washed in Tris-buffered saline with ...
A better understanding of rubber-dampening properties can be gained by looking at the viscoelastic properties of a given compound. The different polymer types provide a better level of dampening based on the polymer structure and chemical chains. During dampening, there is a component of how muc...

Here, the authors have demonstrated that the magnetic and structural properties of a spin-crossover complex,Fe(phen)2(NCS)2(phen=1,10-phenanthroline), can be reversibly switched by the on-off action of the continuous photoexcitation at the same temperature. The structural data suggest that the...
Tuning the Transition Temperature and Cooperativity of bapbpy-Based Mononuclear Spin-Crossover Compounds: Interplay between Molecular and Crystal Engineering In this study, we show that 1)different isomers of the same mononuclear iron(II) complex give materials with different spin-crossover (hereafter ...
aIn the above known process, DEAD is diethylazodicarboxylate and PPh3 is triphenylphosphine. The reactants are stirred at room temperature overnight and the resultant formate ester is converted to the corresponding hydroxy compound with the desired stereochemistry. 在以上已知的过程,死diethylazodicarboxylate...
The solvent was removed under reduced pressure at 10 °C–20 °C to afford the title compound as a white solid (59.0 mg, 98.3 μmol, 98%, 6:94 d.r.). At room temperature, the product undergoes gradual interconversion to (±-trans)-2a and was therefore stored at −20...
